Ramona and Mario Singer have been staples on Bravo’s Real Housewives of New York City show. But, it looks like the couple has separated after 27 years together. Read on for the facts on the alleged split.

UPDATE: Ramona Singer has filed for divorce from her husband Mario and has tweeted to followers, asking for privacy and respect for their daughter Avery during this difficult time.

Thank you all for the love & support! For my daughter's sake, I would appreciate everyone respecting our privacy during this difficult time.

According to legal documents obtained by TMZ, Ramona wants both of the couple’s homes and she says the marriage is “irretrievably broken.”

1. The Cops Were Called To Their Home To Break Up a Domestic Dispute

According to Page Six, the police were called to the couple’s Southampton home to break up a fight the two were having. The quarrel allegedly occurred this past Friday night.

Ramona apparently claimed that Mario tried to choke her, but sources have said that the two did not get into a physical altercation.

2. Reports Are Swarming That The Couple Has Separated

Supposedly, Mario has been staying at the couple’s Southampton home, while Ramona has been staying at their Manhattan apartment. Nonetheless, the couple is allegedly trying to keep up with appearances. There is no word of divorce yet or how their daughter Avery is coping.

3. Both Ramona and Mario Are Supposedly Seeing Other People

Apparently, Ramona and Mario have already moved on:

Page Six reported in October that Mario had been seeing a young socialite, who has since been identified as Kasey Dexter. Meanwhile, Ramona was also seen on a date with a “20-something-looking guy” on Thursday night.

The man Ramona’s supposed to have been seen with has been identified as Travis Millard.

4. In Past Seasons of the New York Housewives, Mario Was Caught Checking Out Other Women

In the first season of the show, Mario was caught by Ramona flirting with a younger woman at a party in the Hamptons. To make matters worse, he wasn’t wearing his wedding ring. In addition to this, in a later season, Mario was caught on camera checking out other women when Ramona was trying to have conversations with him.

Ramona shrugged it all off when asked about it at the reunion episodes. She said there’s nothing wrong with flirting … The couple even renewed their wedding vows in a big ceremony on the show.

5. Mario Has Been Accused of Cheating

Page Six reported in October that Mario Singer had supposedly cheated on Ramona with a socialite and had actually gotten the woman pregnant. Supposedly, the young blonde became pregnant over the summer and Mario paid for her to have an abortion this past August. Rumors are that Ramona told her fellow Housewives stars:

If he’s having an affair, I don’t want to know about it.

We hope the Singers are able to patch things up … The new season of the Real Housewives of New York City begins March 11, 2014 at 9:00 p.m. EST on the Bravo network.

wake up Ramona, once a cheater always a cheater. My heart goes out to you for he probably never stopped seeing the other woman. Mario’s life is changing and when the other girl grows tired of a limp noodle, he will be all alone. Alone from you and alone from his daughter. Such a shame.. Go find someone who wants to grow old with you and who cares about you. He is a fool!
